Title: Impedance matching method in high frequency welding machine
Inventor: ISHIRO SABURO
IPC: B23K13/08
Filed: 1985-11-29
Abstract: PURPOSE:To match the impedance of a circuit to the reference value by comparing with the reference value by operating the impedance from the plate voltage and current of an oscillation circuit and by adjusting the inductance so as to make the difference zero. CONSTITUTION:The impedance Z of an oscillation circuit 2 is operated in an impedance computing element 7 by detecting the plate voltage Ep and current Ip of the oscillation circuit 2 of a high frequency welding machine by voltage and current detectors 5, 6. The capacity of a matching inductance 4 is then adjusted automatically via an operator 11 so that the difference DELTAZ becomes zero by comparing this value Z with the reference impedance Z0 in a comparator 8. Consequently, good welding can be performed all the time by matching the impedance Z of the oscillating circuit 2 to the reference value even in case of the lot being changed.

Filed: 1990-10-05
Abstract: PURPOSE:To suppress a fluctuation in a power level without decreasing the operating speed by selecting a buffer transistor(TR) with a large or a small current drive capability depending on an output level. CONSTITUTION:A threshold level of an inverter 52 is set to a high output level (e.g. 2.2V) of TTL. When an input terminal 3 changes from L to H, an output of an inverter 51 changes from L to H, an NMOS 31 is turned off and since an output of the inverter 52 is logical H, an output of a 2-input NAND 71 goes to L and a PMOS 11 is turned on. In this case, the level of an output terminal 4 changes from L to H and when the level exceeds a threshold level 2.2V of the inverter 52, the output of the inverter 52 goes to L, the PMOS 12 is turned on, an output of a NAND 71 goes to H and a PMOS 11 is turned off. That is, when the level of the terminal 4 changes from L to H, the PMOS 11 with a large current drive capability is selected up to 2.2V to invert the level of the terminal 4. Then the PMOS 12 with a small current drive capability is selected at 2.2V or over to invert the level of the terminal 4.
